What number planet is pluto?

Answer 1

It depends if you count all planets, or just dwarf planets:

• On the list of all 13 planets including dwarf planets, pluto is the 10th from the sun.
  
• If you only count only the 5 dwarf planets, it is the second dwarf planet from the sun (the first is Ceres).
  

Answer 2

In our solar system, Pluto is recognized as the ninth planet from the sun. However, it has somewhat recently been reclassified as a dwarf, not a true planet.
